Now you can use the Docker sync.
In your 'docker-compose-dev.yml' add something like this:
\x1b[0;33m
  app:
    volumes_from:
      - unison
  unison:
    container_name: angular_sync_unison
    image: onnimonni/unison:latest
    environment:
      - UNISON_DIR=/var/www/html
      - UNISON_UID=501 # Default UID of the OSX user; might be overwritten with an .env file
    volumes:
      - /var/www/html
    ports:  
      - \"5000\"
\x1b[0m
Then issue the sync command:
\x1b[0;33m
  ./dosxer_sync
\x1b[0m

For the first time the \x1b[0;33mdocker-compose\x1b[0m command might partially fail b/c there was no initial sync yet. Just start the sync with the \x1b[0;33munison\x1b[0m command and re-issue the \x1b[0;33mdocker-compose\x1b[0m command after the sync was done.
The initial sync might depending on the project size take a while. After that you will have a proper and fast two-way sync."
